古土壤是记录古环境的重要材料，目前在风化成土强度指标选取、定量恢复古气候以及受埋藏影响等方面需加强研究。岷江上游地区晚第四纪环境演变研究缺乏，认识该区环境演变历史不仅能为全球气候变化研究提供案例，而且对深入理解包括研究区在内的“藏彝走廊”古文化变迁历史有重要意义。本课题拟基于现代土壤学理论，结合沉积学、地貌学、元素地球化学等相关理论与方法，对岷江上游地区晚第四纪古土壤进行野外辨识与采样，分析古土壤发生学特征及土壤类型，并建立适合区域研究的土壤发生学特征指标与气候因子的定量关系，从而定性与定量重建古环境历史。在此基础上，结合考古学、历史学等研究成果，探究研究区古文化变迁与环境变化的关系。

Paleosols are ideal archives for paleoenvironment reconstruction. However, the further research should be strenthened on the weathering and pedogenic proxies selection, quantitative paleoclimate reconstruction and effects of burial on paleosols. The knowledges are rare on the late quaternary environmente changes in the upper reaches of the Min River that are important for understanding regional environmental evolution as a local case of global climate change research, and necessary for investigation the ancient culture transition in the Zang-Yi Corridor cluding this study region. Here, an attempt is taken to identify and sample the late quaternary paleosols in the upper reaches of the Min River and integrated investigation on the paleosols is conducted, based on the modern soil sciences combined by the theories and methods of sedimentology, geomorphology and element geochemistry. The investigation content is consisted of the analysis of pedogenesis and type of the paleosols, establishing the quantitative relationship between soil weathering indices and climate agents for qualitative and quantitative reconstruction late quaternary environmental history. In combination with the archives in archaeology and historiography, the relationship between ancient culture evolution and environmental change would be investigated.
